Development trend and performance analysis of PCD tools

2020-01-06


Recently, the development and application of multifunctional rotary cutting machines with PCD tips have increased. This tool can perform drilling, reaming, chamfering, finishing and other multi-hole machining operations at one time. It can be used in the automotive industry to effectively reduce processing costs. Milling cutters are equipped with multiple small blade PCD Inserts that do not need to be reground. The Chip Breaker on the insert allows effective chip control. The cutter body is made of lightweight stainless steel, which can avoid the wear and cooling of aluminum alloy chips, and the injury of the washing machine to the body. The Milling Cutter also integrates a cam-driven axial adjustment device, which can precisely fine-tune the axial size of the PCD insert and achieve a smaller tool hardware structure. With the continuous improvement of the cutting performance of PCD tools and the declining price of PCD tools, PCD tools have unprecedented appeal to users, which will effectively promote the rapid development of the promotion and application of PCD tools and PCD tool technology.

PCD tools for machining aluminum workpieces have the advantages of long life and high finish. Disadvantages are expensive tools and high processing costs. This has become the consensus of the machinery manufacturing industry. However, in recent years, many changes have occurred in the development and application of PCD tools. Today's aluminum materials are not the same in performance. When processing various newly developed aluminum alloy materials, especially high silicon content composite materials, PCD tools must be carefully selected to optimize productivity and processing quality. Grades and geometric parameters can meet different processing requirements. Another change in PCD tools is the continuous reduction in processing costs. Under the combined effect of market competition pressure and improvement of tool manufacturing process, the price of PCD tools has dropped by more than half. The above-mentioned changing trend has led to more and more applications of PCD tools in aluminum material processing, and the applicability of tools is limited by different processing materials.

In the past, high prices have been a major obstacle to the widespread adoption of PCD tools, but the situation has changed dramatically. One of the reasons for the "dip" of PCD tool prices is oversupply in the market. In the early days, the development momentum of PCD tools began to exceed that of traditional carbide tools. In the following decade, the market demand for PCD tools continued to grow. However, as PCD tool manufacturing technology matures, its sales growth momentum has begun to slow. The current downturn in the entire manufacturing industry has also had a certain impact on the PCD tool market. In addition, new competitors entering the PCD tool manufacturing industry have also shaken the existing market price system. Another reason for the decline in the price of PCD tools is the continuous reduction in tool manufacturing costs and the continuous improvement of tool manufacturing processes, such as the EDM process for rough rough diamond cutting and the precision machining of cutting edges. In addition, compared to ten years ago, the quality of diamond grinding wheels for machining PCD Cutting tools has been significantly improved and costs have been greatly reduced.
